Why does K + N2 yield no reaction? could some one please explain what factors contribute to no reaction
Calculate the pH of the solution made by adding 0.50 mol of propanoic acid, (C2H5COOH or HC3H5O2) and 0.30 mol of sodium propanoate (C2H5COONa or NaC3H5CO2) to 1.00 L of water. The value of Ka for C2H5COOH is 1.3 x 10^-5.
How many grams of dry NH4Cl need to be added to 1.50 L of a 0.800 M solution of ammonia,NH3 , to prepare a buffer solution that has a pH
For the copper zinc cell the potential at 25 degrees C is 1.10 volts. The reaction is: Cu++ (aq) + Zn(s) = Zn ++ (aq) + Cu(s) Calculate the equilibrium constant for this reaction (a wire is connected and electrons flow between the electrodes)
How many grams of aluminum chromate are produced from 66.4 grams of aluminum hydroxide?
Draw a flow chart that illustrates how you would purify an organic compound that is contaminated with inorganic solids that are water soluble
Teeth are made principally from the mineral hydroxyapatite, Ca5 (PO4)3OH, which can be dissolved in acidic solution such as that produced by bacteria in the mouth:
confirm that the z-component of orbital angular momentum is a basis for an irreducible representation of A2 symmetry in C3v
It's not until death that the percentage of carbon-14 will begin to diminish from decay. Because radioactive decay is a first-order process, the integrated rate law for a first-order reaction can be rewritten asfraction remaining
The compound MgSO4 is called Epsom salts. How many grams will you need to prepare a bath containing 5.80 moles of Epsom salts? Express your answer using three significant figures.
If the initial concentration of the reactant in a first order reaction is .5 mols/L and the half life is 500 seconds, calculate the concentration of the reactant 1200 seconds after initiation of the reaction?
The rate constant (k) for a reaction was measured as a function of temperature. A plot of ln k versus 1/t (in K ) is linear and has a slope of ?1.13×10^4 K.
Then she added 90ml of water to the same solution making it a total of 100ml and checked the solutions pH and it was 3. Predict the pH of the solution if Amber adds 900ml of water to the solution. Explain why you predicted that pH.
